• November 18, 2025Course 8 - Penetration Testing OSINT Gathering with Recon-ng | Episode 4: Recon-ng Results: Comprehensive Reporting Formats and Strategic

  In this lesson, you’ll learn about:
  Managing Recon-ng Data and Generating Stakeholder Reports This episode provides a complete guide to organizing, reporting, and analyzing the large amounts of data collected in a Recon-ng workspace. The emphasis is on converting raw terminal output into structured reports for stakeholders, and performing the necessary strategic analysis before moving forward with later stages of a penetration test. 1. Generating Organized Reports The first priority is exporting Recon-ng data into formats that can be easily consumed by company administrators, security teams, or management. While the internal show dashboard is useful for the tester’s own overview, it is not suitable for stakeholders. Recon-ng offers several reporting modules to solve this: • CSV Reporting
  

  • The reporting/csv module generates spreadsheet-style output (compatible with Excel, LibreOffice, etc.).
  • By default, this module exports data from the hosts table.

  • JSON and XML Reporting
  

  • The reporting/json and reporting/xml modules allow exporting data in structured formats.
  • Multiple database tables can be included as needed.
  • These formats are ideal for automated pipelines, dashboards, or integrating with other tools.

  • HTML Reporting
  

  • The reporting/html module creates a ready-to-share HTML report.
  • It includes:
    • An overall summary
    • Sections for all database tables that contain data
    • Optional customization using set creator (your company/organization) and set customer (client name, e.g., “BBC”)
  • This format is suitable for emailing or presenting to non-technical stakeholders.

  • Lists
  

  • The reporting/lists module outputs a single-column list from a selected table.
  • The default column is IP address, but it can be changed (e.g., region, email addresses, etc.).
  • Useful for feeding data into other tools or scripts.

  • Pushpin (Geolocation Viewer)
  

  • A more visual reporting option.
  • When latitude, longitude, and radius are set, this module generates HTML files showing pushpins on a Google Maps interface.
  • Useful for mapping physically geolocated server infrastructure.

  All reports reflect the contents of the currently active workspace, so organizing your data beforehand is important. The Python source files defining each reporting module can be inspected within the Recon-ng home directory if needed for customization or learning. 2. Strategic Post-Scan Analysis (Critical Thinking Phase) After exporting the collected data, the episode stresses that a deliberate analytical stage is absolutely essential. Without it, the reconnaissance effort “is pretty much useless.” This stage involves interpreting the findings and evaluating their security implications. Key analysis areas include: • Infrastructure Weakness Identification
  

  • Reviewing BuiltWith data and other technical findings.
  • Understanding the technologies, frameworks, CMS versions, and hosting setups being used.
  • Assessing how an attacker could target these components.

  • Social Engineering Exposure
  

  • Reviewing publicly accessible HR contacts, admin emails, employee names, and roles.
  • Determining how attackers could misuse this information for phishing or impersonation.

  • Public Information Scrubbing
  

  • Evaluating which data points should be removed from public sources.
  • Prioritizing sensitive or high‑risk information that exposes the organization.

  • Policy and Organizational Review
  

  • Determining whether internal security policies need updates.
  • Assessing whether operational structures expose unnecessary attack vectors.

  This stage turns raw data into actionable security recommendations. 3. Next Steps in the Penetration Testing Process Once the reporting and analysis stages are complete, the workflow naturally progresses to the next technical phases: • Vulnerability Assessment
  

  • Using external vulnerability scanners such as OpenVAS.
  • Identifying misconfigurations, outdated software, missing patches, and other weaknesses.

  • Exploit Phase
  

  • After identifying vulnerabilities, controlled exploitation attempts are performed.
  • These follow strict ethical guidelines and client permissions.

• November 17, 2025Course 8 - Penetration Testing OSINT Gathering with Recon-ng | Episode 3: Harvesting Data, Optimizing Contacts, Geolocation

  In this lesson, you’ll learn about: Conducting a Multi‑Stage OSINT Campaign Using Recon‑ng 1. Initial Data Harvesting & Database Population The OSINT campaign begins by creating a dedicated workspace and planning the stages of information gathering. The first objective is to populate core database tables—contacts and hosts. Contact Gathering

  • whois_pocs module collects domain registration information, extracting email addresses and owner details.
  • PGP search modules identify additional contacts by searching for PGP keys associated with the target domain.

  Host Discovery

  • bing_domain_web module scans the domain to enumerate subdomains and hostnames.
  • brute_hosts module brute‑forces common hostnames to uncover additional active hosts not found through search engines.

  File Analysis

  • Once the hosts table is filled, the interesting_files module scans discovered hosts for publicly accessible files such as:
    • sitemap.xml
    • phpinfo.php
    • Test files
      These files may contain operational details useful for further analysis.

  2. Contact Optimization & Breach Assessment This phase enhances collected contact data and checks whether employees or organizational accounts have been compromised. Email Construction Using Mangle

  • The mangle module builds complete email addresses using partial names and organizational naming patterns.
  • It combines first/last names with the domain to produce likely valid addresses.

  Breach Monitoring Using HIBP

  • hibp_breach module checks if collected or constructed emails were exposed in known credential leaks.
  • hibp_paste module searches paste sites for leaked emails or credentials.
  • Any hits are stored in the credentials table for responsible reporting and remediation.

  3. Geolocation of Target Servers This stage identifies the physical locations of the target’s online infrastructure. IP Resolution

  • The resolve module converts hostnames into IP addresses and updates host entries.

  Geolocation

  • The free_geoip module geolocates IPs, revealing the server’s approximate city, region, and country.
  • Location details are appended to the host’s database record.

  Shodan Integration (Optional)

  • When a Shodan API key is available:
    • Latitude/longitude data is used by the shodan module to gather additional OSINT such as services, banners, and exposed ports.

  4. Comprehensive Software Stack Profiling The final stage performs a deep analysis of the technologies behind the target website. BuiltWith Technology Scan

  • The BuiltWith module identifies:
    • Web technologies (e.g., Apache, Nginx, Ubuntu)
    • Infrastructure providers (e.g., AWS)
    • Associated tools (jQuery, New Relic, Analytics services)
  • For large domains, the scan may return hundreds of data points, greatly enriching the OSINT profile.

  Additional Discoveries

  • Administrative contacts
  • Social media integrations
  • CDN details
  • Heat‑mapping and analytics tools (e.g., Mouseflow)
  • Optimization platforms (e.g., Optimizely)

  Summary By the end of this lesson, students understand how to conduct a complete OSINT workflow using Recon‑ng:

  • Populate key database tables
  • Form accurate contact and host profiles
  • Identify data breaches ethically
  • Geolocate infrastructure
  • Profile the full technology stack of a target domain

  This staged approach reflects real-world ethical OSINT methodology and supports responsible security research.

• November 16, 2025Course 8 - Penetration Testing OSINT Gathering with Recon-ng | Episode 2: Modules, Data Flow, Naming Structure, API Keys

  In this lesson, you’ll learn about: Mastering Recon-ng Module Operations, Data Flow, Naming Structure, API Integration & Session Automation 1. Understanding Module Functionality To operate any module correctly, analysts must inspect its requirements using:

  • show info — displays the module’s:
    • Name
    • Description
    • Required and optional inputs
    • Source and destination database tables

  This command is essential before running any module because it defines what data the module needs and what data it will produce. 2. Data Flow and Interaction Recon-ng modules depend heavily on structured input/output flows:

  • Modules read from specific database tables (e.g., domains, hosts)
  • Then write results to other tables (e.g., contacts, repositories)

  Understanding this flow is critical for chaining modules efficiently. 3. Module Chaining and Dependency Modules are often dependent on data gathered by earlier modules. Examples:

  • Use a domain enumeration module (e.g., google_site_web)
    → populates the hosts table
  • Then run a discovery module (e.g., interesting_files)
    → requires the hosts table to be populated to search for files

  This process is known as module chaining, forming a structured intelligence pipeline. 4. Database Querying Recon-ng allows advanced database searches:

  • query command → perform SQL-like lookups
  • run + SQL syntax → filter large datasets

  Example use case:
  Retrieve contacts belonging to one domain instead of dumping the entire contacts table. This improves workflow efficiency when processing large OSINT datasets. 5. Module Configuration Modules can be customized using:

  • set → assign a value (e.g., limit results, pick target subdomains)
  • unset → remove the assigned value

  Modules also store collected artifacts (such as downloaded files) inside the workspace directory under the .recon-ng path. 6. Module Naming Structure Recon-ng organizes modules into logical categories such as:

  • Reconnaissance
  • Reporting
  • Import
  • Discovery

  The naming scheme for Reconnaissance modules is especially important:

  • Each module name reflects the source → destination flow
    • Example: domains-hosts means “take domains and discover hosts”
  • Common tables used include:
    • companies
    • contacts
    • domains
    • hosts
    • netblocks
    • profiles
    • repositories

  This structure makes it easy to understand what each module does simply from its name. 7. API Key Management Some modules rely on external APIs (e.g., BuiltWith, Jigsaw). Key commands:

  • keys add → configure an API key
  • show keys → list all installed keys

  Without keys, these modules will fail or return limited data. 8. Session Scripting & Automation Recon-ng supports automation to streamline repetitive assessments. Tools covered include: a. Command Recording

  • record start → begin recording commands
  • record stop → stop recording
  • Run recorded script using:
    recon-ng -r

  This allows you to reproduce actions automatically. b. Full Session Logging

  • spool → log everything output in the session
    Useful for audits, reporting, and compliance documentation.

  Summary This lesson teaches students how to:

  • Understand module requirements (show info)
  • Chain modules effectively using database-driven workflows
  • Customize modules with set and unset
  • Use Recon-ng’s SQL-like querying for precise data extraction
  • Manage API keys for enhanced OSINT data
  • Automate tasks using recording and spooling

  Mastering these concepts is essential for efficient Recon-ng usage in real-world penetration testing and intelligence operations.

  • Purpose: Simulate attacks on running software to observe responses.
  • Focus Areas:
    • SQL Injection
    • Cross-site scripting (XSS)
    • Misconfigured servers
  • Goal: Test behavior of deployed applications under attack conditions.

  D. Fuzzing

  • Type: Black-box testing
  • Purpose: Identify bugs or vulnerabilities by injecting invalid, random, or malformed data.
  • Applications: Protocols, file formats, APIs, or applications.
  • Goal: Detect errors that could lead to denial of service or remote code execution.
  • Categories:
    • Application fuzzing
    • Protocol fuzzing
    • File format fuzzing

  E. Penetration Testing (Pentesting)

  • Purpose: Simulate real-world attacks to find vulnerabilities automated tools might miss.
  • Phases:
    1. Reconnaissance: Gather information about the target.
    2. Scanning: Identify open ports, services, and potential attack surfaces.
    3. Gaining Access: Exploit vulnerabilities to enter the system.
    4. Maintaining Access: Test persistence mechanisms.
    5. Covering Tracks: Evaluate if an attacker could erase traces.

  F. Open Source Security Analysis (OSA/SCA)

  • Purpose: Identify vulnerabilities in open-source components used by the application.
  • Process:
    1. Create an inventory of open-source components.
    2. Check for known vulnerabilities (CVEs).
    3. Update components to patch vulnerabilities.
    4. Manage the security response to reported issues.

  3. Manual vs. Automated ValidationAspectManual ValidationAutomated ValidationExpertiseRequires high domain expertiseEasier for non-expertsSpeedSlow and time-consumingFast and scalableCoverageCan be very thoroughLimited by supported languagesAccuracyAccurate, less false positivesMay generate false positivesBest UseComplex logic, new attacksRoutine checks, high-volume scans
  
  Recommendation: Use a hybrid approach, combining both manual expertise and automated tools for comprehensive security coverage. 4. Summary

  • Secure Validation is critical for detecting vulnerabilities before deployment.
  • Techniques include SAST, IAST, DAST, fuzzing, pentesting, and OSA/SCA.
  • Combining manual and automated methods ensures accurate, fast, and comprehensive vulnerability detection.

The objective is to develop, deploy, and release software with continuous security and automation. 2. Secure Deployment and Infrastructure Hardening Key practices for secure deployment include:

  • Infrastructure Hardening: Follow CIS benchmarks to reduce risk across hardware and software.
  • Principle of Least Privilege: Grant only necessary access and revoke unnecessary permissions.
  • Access Control: Enforce strong authentication, restrict network access via firewalls, and monitor system access and network IP addresses.
  • Patching and Logging: Apply security patches based on CVE tracking, and implement auditing and logging policies.
  • Secure Connections: Enable TLS 1.2/1.3, use strong ciphers and secure cookies, and implement SSO or MFA as needed.

  3. Secure DevOps (DevSecOps) DevSecOps integrates security throughout the DevOps pipeline. Key considerations:

  • Automation: Increases efficiency, reduces human error, and ensures consistent security checks.
  • Tool Integration: Combine SAST/IAST and WAFs with issue tracking (e.g., Jira) for continuous monitoring.
  • Compliance Automation: Identify applicable controls and automate compliance measurement within the SDLC.
  • Monitoring Metrics: Track deployment frequency, patch timelines, and the percentage of code tested automatically.

  4. Secure Container Deployment Containers introduce unique security risks. Recommended practices include:

  • Code Scanning and Testing: Use static analysis tools and check for vulnerable dependencies.
  • Admission Control: Block unsafe container images, e.g., those exposing passwords.
  • Privilege Restriction: Run containers with minimal privileges; avoid root or privileged flags.
  • System Calls and Benchmarks: Limit powerful calls like Ptrace and ensure hosts meet CIS benchmarks for Docker/Kubernetes.

  5. Web Application Firewall (WAF) A WAF protects web servers by inspecting, filtering, and blocking HTTP traffic at Layer 7.

  • Protection Capabilities: Mitigates threats like SQL injection, XSS, and file inclusion; supports OWASP Top 10 protection.
  • Security Models: Blacklist (negative), whitelist (positive), or hybrid.
  • Deployment Strategy:
    • Ensure WAF meets application security goals
    • Test alongside RASP or DAST tools
    • Integrate with SIEM and security workflows
    • Support compliance (PCI, HIPAA, GDPR)

  6. Secure Review Practices Five key pre-deployment review steps:

  1. Gap Analysis: Compare policies against NIST Cybersecurity Framework (Identify, Protect, Detect, Respond, Recover).
  2. Privacy Review: Assess potential privacy violations and mitigation strategies.
  3. Open-Source Licensing Review: Confirm license compliance and categorize risks (low, medium, high).
  4. Security Test Results Review: Address vulnerabilities from SAST, IAST, WAF prior to release.
  5. Certify the Release: Document and control software releases using a formal approval process.

  7. Continuous Vulnerability Management (CVM) CVM ensures ongoing risk reduction by identifying and remediating vulnerabilities continuously:

  • Scanning and Patching: Use SCAP-compliant tools like Nessus, Rapid7, or Qualys; apply updates via automated tools (e.g., SolarWinds Patch Manager, SCCM).
  • Vulnerability Tools: Schedule recurring network scans, define targets, and manage scan plugins to optimize performance.

  8. Summary

  • Secure Deployment ensures that security is embedded in the release process.
  • Integrates practices from infrastructure hardening, DevSecOps, container security, WAF deployment, secure reviews, and CVM.
  • Moves beyond checklists to continuous, automated risk management, ensuring deployed systems remain secure.
